Introduction; Safety - Mitsubishi Electric D700 Quick Start Manual

1. INTRODUCTION

This Quick Start Manual provides instructions for advanced use of
the FR-D700 series inverters. Incorrect handling might cause an
unexpected fault. Before using the inverter, always read this Manual
carefully to use the equipment to its optimum performance. Please
forward this Manual to the end user.
NOTE: Many of the diagrams and drawings in this Manual show the
inverter without a cover, or partially open. Never operate the inverter
in this manner. Always replace the cover and follow this Manual when
operating the inverter.

1.1 SAFETY

Do not attempt to install, operate, maintain or inspect the inverter until
you have read through the Quick Start Manual carefully and can use
the equipment correctly. Do not use this product until you have a full
knowledge of the equipment, safety information and instructions. In
this Installation Guideline, the safety instruction levels are classified
into "DANGER" and "CAUTION".
DANGER
Indicates that incorrect handling may cause
hazardous conditions, resulting in death or severe injury.
CAUTION Indicates that incorrect handling may cause
hazardous conditions, resulting in medium or slight personal injury
or physical damage.
Depending on the circumstances, procedures indicated by
may also cause severe injury. It is important to follow all precautions for
personal safety.
DANGER ELECTRIC SHOCK PREVENTION
• While power is on or when the inverter is running, do not open the
front cover. Otherwise you may get an electric shock.
• Do not run the inverter with the front cover or wiring cover removed.
Otherwise, you may access the exposed highvoltage terminals or
the charging part of the circuitry and get an electric shock.
• Even if power is off, do not remove the front cover except for wiring
or periodic inspection. You may access the charged inverter circuits
and get an electric shock.
• Before starting wiring or inspection, switch off power, check to make
sure that the operation panel indicator is off, wait for at least 10
minutes after the power supply has been switched off, and check
that there are no residual voltage using a tester or the like. The
capacitor is charged with high voltage for some time after power off
and it is dangerous.
• This inverter must be earthed (grounded). Earthing (grounding) must
conform to the requirements of national and local safety regulations
and electrical code. (NEC section 250, IEC 536 class 1 and other
applicable standards)
• Any person who is involved in the wiring or inspection of this
equipment should be fully competent to do the work.
• Always install the inverter before wiring. Otherwise, you may get an
electric shock or be injured.
• Perform setting dial and key operations with dry hands to prevent an
electric shock. Otherwise you may get an electric shock.
• Do not subject the cables to scratches, excessive stress, heavy
loads or pinching. Otherwise, you may get an electric shock.
• Do not change the cooling fan while power is on. It is dangerous to
change the cooling fan while power is on.

• Do not touch the printed circuit board with wet hands. Otherwise,
you may get an electric shock.
• When measuring the main circuit capacitor capacity, the DC voltage
is applied to the motor for 1s at powering off. Never touch the motor
terminal, etc. right after powering off to prevent an electric shock.
CAUTION FIRE PREVENTION
• Install the inverter on a nonflammable wall without holes (so that
nobody can touch the inverter heatsink on the rear side, etc.).
Mounting it to or near combustible material can cause a fire.
• If the inverter has become faulty, switch off the inverter power. A
continuous flow of large current could cause a fire.
• When using a brake resistor, make up a sequence that will turn off
power when an alarm signal is output. Otherwise, the brake resistor
may excessively overheat due to damage of the brake transistor and
such, causing a fire.
• Do not connect a resistor directly to the DC terminals P/+ and N/-.
This could cause a fire.
CAUTION INJURY PREVENTION
• Apply only the voltage specified in the instruction manual to each
terminal. Otherwise, burst, damage, etc. may occur.
• Ensure that the cables are connected to the correct terminals.
Otherwise, burst, damage, etc. may occur.
• Always make sure that polarity is correct to prevent damage, etc.
Otherwise, burst, damage, etc. may occur.
• While power is on or for some time after power-off, do not touch the
inverter as they will be extremely hot. Doing so can cause burns.
CAUTION
CAUTION INJURY PREVENTION
• Also note the following points to prevent an accidental failure, injury,
electric shock, etc.
• Transport the product using the correct method that corresponds to
the weight. Failure to observe this could lead to injuries.
• Do not stack the inverter boxes higher than the number
recommended.
• Ensure that installation position and material can withstand the
weight of the inverter. Install according to the information in the
instruction manual.
• Do not install or operate the inverter if it is damaged or has parts
missing.
• When carrying the inverter, do not hold it by the front cover or setting
dial; it may fall off or fail.
• Do not stand or rest heavy objects on the product.
• Check the inverter mounting orientation is correct.
• Prevent other conductive bodies such as screws and metal
fragments or other flammable substance such as oil from entering
the inverter.
• As the inverter is a precision instrument, do not drop or subject it to
impact.
• Use the inverter under the following environmental conditions:
Otherwise, the inverter may be damaged.
